For me, the content created by communities that is exclusively available on that site is really helpful to me. If possible I would definitely try and archive a few subreddits and write something to search and access it offline (sorta like https://en.wikipedia.org/wiki/Kiwix but for reddit).
Which is really sad when you think about it. It’s a blow to our collective knowledge.
This is my dilemma. Deleting the data may prevent reddit from profiting off of it, sure, but then where does the knowledge and very specific case tech support of the past half a decade go? Would appreciate all those posts being mass edited and deleted to at least be preserved on the wayback machine.
